THREADLESS NUT-LOCK.

Specification of Letters Paten. Patented Sept. 6, 1910.

Application filed April 24, 1908. Serial No. 429,031.

To all whom it may concern: Be it known that I, GEORGE W. citizen of the United States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented a new and useful Threadless Nut-Lock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 'the same. o

The invention relates to improvements in bolts and nuts and has for its object to provide a simple, durable and inexpensive device of this character constructed without BACON, a

threads and which can be quickly applied to a rail joint or the like.

In the drawings, Figure l is a perspective view of the device. thereof. Fig. 3 is an elevation of the same. Fig. 4 is a plan view partly in section with certain parts removed.- Fig. 5 is a vertical section of the device to the parts shown in locked position. Fig. 6 is' a detailed perspective view of the nut locking member.

Referring to the drawings 1 designates a bolt of the ordinary construction, but without threads, and in their stead, oppositely arranged lateral extending lugs 2 are provided. A transverse aperture or opening 3 extends at an angle to the lugs, and through the shank of the bolt, which is adapted to receive the member or pin 6, for the purpose hereinafter set forth.v

4 designates a nut, provided with oppositely arranged inclined upper faces 5, as is clearly shown in Figs. 1 and 6. This nut is provided with an opening 7, for the reih ception of the said bolt. The said nut is further provided with recesses 4 arranged diagonally one another upon either side of the said opening 7, adapted to admit of the said lugs 2, which lugs after passing through the said recesses are thrown out of registration with the recesses, b virtue of the bolt which may be turned s cient to accomplish this action, and which prevents accidental removal of the said bolt.

together,

Fig. 2 is a plan View in- Fig. 1 as .of these openings 1 are recesses 1, which are adapted to register with the recesses 4, when it is desired to clamp the two plates by virtue of the nut and bolt.

The bolt 1 is provided with the usual head 1 which is designed to engage the face of one of the plates, while the nut 4 is adapted to engage the face of the other plate. When the parts of the applicants device are assembled as shown in Fig. 1, the bolt 1 has been turned sufiicient to move the lugs 2 out of registration with the said recesses, and also suflicient to cause the member or pin 6 to frictionally engage the inclined faces of the nut, so as to clamp the plates securely together.

What is claimed is, I

The combination of a bolt and nut, said nut having an opening to receive the end of said bolt and provided with oppositely arranged recesses, said bolt having oppositely arranged lugs adjacent to its end adapted to engage said recesses when the nut is being applied to the bolt, said nut having oppositely disposed inclined upper faces, said bolt having versely thereof and adjacent its end, and at an angle to the disposition of said lugs, a key penetrating said aperture adapted to be engaged by the said inclined upper faces so that when thebolt or nut is rotated in a certain direction the bolt or nut will be drawn ome.

In testimony whereof I have signed my 'name to this specification in the presence of two subscribing witnesses.
